Kinematics of erosion-induced landslide mobility
Shiva P. Pudasaini
Erosion-induced landslide mobility is a prominent phenomenon in nature. However, this topic remains poorly understood, even though erosion greatly alters nearly every aspect of lan…
The landslide drag
Shiva P. Pudasaini
Drag is one of the most important energy dissipation mechanisms in nature, including landslides and debris flows. To satisfactorily reproduce laboratory or field data in simulating…
The Frictional Brachistochrone
Shiva P. Pudasaini
Here, I construct an elegant frictional brachistochrone for a mass point motion of a granular material with the Coulomb frictional energy dissipation that inherently includes the e…
A multi-phase thermo-mechanical model for rock-ice avalanche
Shiva P. Pudasaini
We propose a novel multi-phase thermo-mechanical rock-ice avalanche model. It considers rock, ice and fluid; includes rigorously derived ice melt rate, melting efficiency dependent…
Unified Mechanical Erosion Model for Multi-phase Mass Flows
Shiva P. Pudasaini
Erosion poses a great challenge in multi-phase mass flows as it drastically changes flow behavior and deposition pattern by dramatically increasing their masses, adversely affectin…
Extended landslide velocity and analytical drag
Shiva P. Pudasaini
The landslide velocity plays a dominant role in estimating impact force and devastated area. Here, based on Pudasaini and Krautblatter (2022), I develop a novel extended landslide…
P-Index
Shiva P. Pudasaini
I propose the P-Index that genuinely constitutes a well-defined, compact author citation metric.
Dispersive landslide
Shiva P. Pudasaini
Considering the non-hydrostatic mass flow model (Pudasaini, 2022), here, we derive a novel dispersive wave equation for landslide. The new dispersive wave for landslide recovers th…
A Non-Hydrostatic Multi-Phase Mass Flow Model
Shiva P. Pudasaini
Modeling mass flows is classically based on hydrostatic balance equations. However, if momentum transfers scale similarly in slope parallel and flow depth directions, then the grav…
The Mechanics of Landslide Mobility with Erosion
Shiva P. Pudasaini, Michael Krautblatter
Erosion, as a key control of landslide dynamics, significantly increases the destructive power by rapidly amplifying its volume, mobility and impact energy. Mobility is directly li…
The Landslide Velocity
Shiva P. Pudasaini, Michael Krautblatter
Proper knowledge of velocity is required in accurately determining enormous destructive energy of a landslide. We present the first physics-based general analytical landslide veloc…
A mechanical model for phase-separation in debris flow
Shiva P. Pudasaini, Jan-Thomas Fischer
Understanding the physics of phase-separation between solid and fluid phases as a mixture mass moves down slope is a long-standing challenge. Here, we propose an extension of the t…
A mechanical erosion model for two-phase mass flows
Shiva P. Pudasaini, Jan-Thomas Fischer
Erosion, entrainment and deposition are complex and dominant, but yet poorly understood, mechanical processes in geophysical mass flows. Here, we propose a novel, process-based, tw…
